US PGA CHAMPIONSHIP ESSENTIALS

Oak Hill in upstate New York hosts the year's fourth and final major and if the previous three are anything to go by we should be in for another belter.

US PGA CHAMPIONSHIP ICONS

Use our icons to keep up with the action. We've got an eagle, a tiger and a birdie that goes 'tweet'. Scroll to the foot of the article for a full key.

Adam Scott (Masters), Justin Rose (US Open) and Phil Mickelson (The Open) scooped the big ones in 2013 and one man is desperate to join the party. Tiger Woods has not won a major since his 14th in 2008 but the world No 1 arrives in fine form after running away with the WGC-Bridgestone Invitational for a fifth victory of the season.

Elsewhere, Rory McIlroy is the defending champion and Lee Westwood has a chance to bounce back from throwing away a final-round lead at Muirfield last month.

Make sure you stick with MailOnline Sport as we bring you all the action as it happens, the latest news, live scores and all the best pictures.

12am: That's your lot for round two. The day belonged to Dufner but how will tomorrow pan out?

Tom Bellwood will be here on Saturday afternoon to take you through all of the action as it happens.

Good night.

11.44pm: It's a 68 for Furyk after a par at the last. He's two behind Dufner along with Scott and Kuchar.

11.32pm: The form man Stenson is feeling the strain of finishing in the top three in each of his last three events - the Scottish Open, Open and Bridgestone Invitational. After a 66 that gave him a six-under total, he told Sky Sports: 'I was tired yesterday, more mentally than physically. It takes a bit out of you when you're up there contending.'

Furyk finds the 17th just too tough and he's back to two behind after a bogey.

11.24pm: We're getting close to the end. But it also means we're getting closer to the start of the third round and there will be some top-drawer pairings going out on Saturday. We'll have them for you as soon as they're announced.

11.16pm: Woods has had his struggles today but he's back to level par after his birdie putt at 17 - the hardest hole on the course - sneaks in the side door.

11.10pm: Furyk rolls in a birdie putt from about five feet on 16 and he's one off the lead again while Sergio Garcia takes three at the 18th to sign for a 68 and a three-under total.

Nice one son: Steve Stricker congratulates Jason Dufner after his round of 63 set a new course record

11.05pm: McDowell pars the last for a 69 and he's one under gong into the weekend. A 72 took casey in the wrong direction and he passed David Lynn on the way down. Lynn, a distant second to McIlroy at Kiawah Island 12 months ago, has birdied four and five to reach three under.

11pm: Dufner looked back on the missed putt for a 62. He told Sky Sports: ''It was tough. I knew 62 hadn't been done in a major. I couldn't have asked for a better putt but I just didn't commit to it. It's been a tough Friday and I'm really looking forward to the weekend.'

10.50pm: It's a two-shot lead for Dufner as Kuchar bogeys the last. It's all going Jason's way. If you fancy him to still be sitting on the summit by Sunday night, you can still get 6-1.

10.40pm: Noooooooo! What a time to leave one short. Dufner's putt is probably his worst of the day but he should tap in for a 63, a new course record. And he does.

10.33pm: Dufner gets the first bit right at 18, finding the short stuff wit his tee shot and his second is like all his others - straight at the pin. He's got about 15 feet up the hill for a place in the history books.

Things are looking up: Jason Dufner sits on top of the leaderboard after shooting 63 in his second round

10.30pm: Woods' putt is almost the length of the green at 14 and there's a bit left in the one back for birdie. It's a three-putt as he catches the left lip. Not a happy Tiger.

10.20pm: If anyone can, Tiger can. Woods manages to hit and hold the green with his tee shot at the par-four 14th. I can't remember anyone else finding the putting surface today. Dufner gives it a good roll at the 17th but it stays out and he's off to the last needing a par for the course record. A birdie and he'll be the first man to shoot 62 in a major.

Like an arrow: Jason Dufner played a flawless round as he fired a course-record 63

10.12pm: A superb second at 16 leaves Kuchar a tap-in to reach eight under while Dufner remains on course to beat the course record - held by Ben Hogan, Curtis Strange and after today's heroics, Simpson.

Dufner's approach to the 17th has left a look at a birdie but two pars will be enough for a 63.

10.02pm: No problem for Dufner. He leads by two after rolling in his putt at 16 while up ahead Garrigus, who bogeyed 17, misses a short putt for par at the last to drop back to five under.

9.54pm: Dufner is all over the flag again. Closer at 16 than he was at 15 after another perfect iron shot in. Can he make this one and open up a two-shot lead before taking on difficult closing holes? McDowell makes it into the red figures as an 18-foot putt falls at the 14th.

9.45pm: A player we haven't mentioned - Jonas Blixt. He's birdied nine and 10 to join his fellow Swede Stenson and putting machine Steve Stricker on five under.

That's more like it: The later starters played under blue skies after rain had hammered the early risers

9.35pm: Dufner's definitely in the mood. His tee shot at the 15th is a cracker, using the little bank at the back and rolling close. It's another birdie chance. He gets the line but it pulls up short just as Kuchar moves within one, getting up and down from the rough just short of the 14th.

9.25pm: It's starting to unravel for Casey. He's off target and in the drink with his tee shot at the par-three 15th. He gets up and down to drop just the one shot. Back at the 10th, finally Furyk finds another birdie. Remember he had one ages ago, at the first. Well, after eight straight pars, Slim Jim is within one of Dufner's lead.

9.15pm: Mickelson knows it's going to take something special for him to land a second major in succession. the Open champion, after two rounds of 71, said: 'I have got to go low tomorrow. I have got to shoot six or seven under par to have a chance on Sunday.'

Swede dreams: Henrik Stenson continued his good recent form at the US PGA Championship

9.09pm: Looks like Dufner fancies flying solo. His approach to the 13th is a beauty and he's got about seven or eight feet for a birdie and the lead on his own. Straight in. Dufner, or as Butch Harmon calls him 'the Duffmeister' leads on his own. We'll stick to Jason.

9pm: McDowell can't get back among the birdies as his putt on 11, after a tee shot to about eight feet, stays above ground but Kuchar has a chance to reach six under after firing a sand wedge to about 10 feet at the 12th. Make that 15 feet. A tougher test but one Kuchar passes. He's within one.

Steady: Jim Furyk was hanging around the top of the leaderboard with two birdies and eight pars

8.51pm: Tiger's long putt sails past and he's got about four feet coming back for par. No worries as he knocks it in while Casey misses a good birdie chance at the par-five 13th.

8.47pm: Woods throws his club and looks away in disgust as his approach to the eighth finishes in the middle of the green. I would have been high-fiving anyone within touching distance after that. Is the dummy about to be spat out? At the moment we're looking at three over for the cut with 77 players on the mark or better.

8.40pm: Woods taps in his tiddler for par at the seventh. It's about seven feet for Dufner to make birdie at 11 and join the leaders and he gives it just enough to fall in. Garrigus and Scott have company.

Stenson moves to within two with a birdie at the eighth.

Play time: Keegan Bradley and Tiger Woods share a joke as they walk off the sixth green

8.31pm: Dufner could be about to join the leaders. His tee shot at the 234-yard 11th is straight at the pin and finishes a few feet short. And still no smile. Well, maybe just a little one but he's playing it cool. Or miserable. Tiger couldn't make the green in two at the seventh but his third, from the rough again, leaves him a putt for par.

8.22pm: Tiger's still got a long way to go but he's making his move. He rolls one in at the sixth for a second birdie on the bounce and he's back to level. Still not firing from the tee though as his iron off the seventh finds the second cut.

8.15pm: G-Mac makes his eight-foot birdie putt at the eighth and he's back to level par and Casey has undone all his good early work. back to level for the day after a bogey on 11.

Taking aim: Jason Dufner had the top of the leaderboard in his sights during his second round at Oak Hill

8.07pm: Unbelievable. After back-to-back bogeys and missing from seven feet at the 10th, Garrigus nails one from at around 25 feet at the 11th to rejoin Scott at the top of the pile on seven under.

8.06pm: Henrik Stenson's round has kicked into life. The Swede, top three in his last three outings, birdies four and five while Graeme McDowell, one over for the day and the tournament, has a chance to get back to level after firing his approach in close at eight.

7.59: Kooch is looking good. His approach to eight spins back to a few feet from the hole and sets up the chance to move within one of the lead. But he doesn't take it and stays two back. A weak effort with the putter from Kuchar.

Doing it the hard way: Tiger Woods found a bunker at the second as he made an unsteady start on Friday

7.50: Casey lets another one go as a par putt at the ninth, from a few feet, fails to reach the hole. That's two in three holes but he's still within three of the lead. Garrigus is also having a bit of a wobble as his second at the 10th is heavy and way short. The chip on leaves seven feet but he can't make the putt and Scott leads on his own once more.

7.37: Now that Garrigus is out on his own, we'll have another price check. He was 300-1 on Thursday morning but the best you're getting now is 20s. Kuchar was more fancied and it's easy to see why. Kooch has found a second birdie of the day, at the sixth, to go five under.

7.32pm: Garrigus leads on his own after a long, long putt falls at eight. That's five birdies for the day. Tiger is not roaring. In fact, he's not even shouting when 'fore' should have been the cry after another wayward tee shot at the fourth.

Plotting their way round: Robert Garrigus and his caddie Brent Henley line up a putt

7.28pm: Casey's charge hits the buffers when he gets caught in the rough next to the seventh green. His chip barely make the putting surface and it's a first bogey of the day.

7.25pm: Twitter's been quieter than usual but we knew we'd get one man on. Poulter, after a birdie-birdie finish for a 71 and a one-over total, said: 'Glad to make 2 birdies to finish. Still p****d off with the end result though. Played really nice golf. Weekend charge is in order.'

7.14pm: Casey is cruising. His tee shot at the par-three sixth lands about seven feet from the hole and the putter is hot for three in a row. He joins his fellow Englishman Rose and American veteran Furyk just one behind Garrigus and Scott. It's getting a bit crowded up there.

There's a new man in charge: Robert Garrigus stormed his way to the top of the leaderboard early in round two

Garrigus saves par with a good up-and-down at the eighth but Woods, after missing another fairway off the tee, bogeys the second to go two over. It could be a long day for the world No 1.

7.10pm: Jim Furyk's birdie putt at the first was too long to even think about guessing the distance. No matter, it rattles the back of the cup and drops to take him to within one. And Dufner joins the party one back as a second straight birdie putt falls for him at the fifth.

Big finish: Ian Poulter birdied the last two holes of his second round to boost his chances at Oak Hill

7.04pm: Scott's probably sitting down, having a bite to eat but Garrigus is determined to spoil his lunch. A fourth birdie in his first six holes and he's in a share of the lead. This is the same Garrigus who, in his last seven events has missed five cuts, withdrew once and finished in a tie for 64th.

7.01pm: The few feet Tiger left was more like 15. Not that it mattered though as the putt was perfect and he got away with that slack tee shot. Casey moves to within a couple of the lead, making no mistake with a three-foot birdie putt at the fifth.

6.55pm: Dufner's dream start continues with a HUGE putt at the fourth finding the cup for birdie. He's two behind. Tiger can only chop his second out of the rough at the first but his third is more like him and he's left a few feet for par.

6.52pm: Some people are never happy. He's leading the US PGA Championship and on track for a second major of 2013 but Scott was cursing the ones that got away. He said: 'There was lots of good stuff but it was a little bit of a mixed bag. It was tough in the rain but that was the holes I played better. I felt I left a few out there.'

6.50pm: Tiger Woods has work to do and he's made his job even harder. He takes a three wood off the first tee and the ball disappears into the long, lush rough. Up ahead, a third birdie in five holes - thanks to a putt from around 20 feet - takes Garrigus on to six under.

And we're off: Tiger Woods on the first tee ahead of the start of his second round at Oak Hill

6.44pm: Rose, who went out in 37 and back in 29, told Sky Sports: 'With the weather and my game, my front nine was a struggle. But it stopped raining, the waterproofs came off, there were no more excuses and everything went my way. Playing with Adam helps. Making birdies didn't seem abnormal. At one point he looked uncatchable but I'm delighted to be a shot behind.'

As rose was talking us through his game of two halves, Casey's eagle putt stops an inch before the hole. He's four under.

6.41pm: Paul Casey's just hit two absolute screamers. After three straight pars, his drive at the par-five fourth cuts the corner and his second, with a fairway wood, finishes about nine feet from the hole. He's three under, but not for long...

6.30pm: Scott's 18-foot birdie effort at the ninth tickles the lip and he has to settle for par. It's a 68 and a lead of just one as Rose birdies the same hole for a 66.

Big guns: Major winners Adam Scott, Justin Rose and Phil Mickelson made up the marquee group

6.23pm: McIlroy, after four birdies in his last seven holes kept is defence of the title alive, said: 'I'm feeling very positive. I was out of the tournament at one point and the way I played the last few holes cheers me up and keeps me positive going into the weekend.'

Meanwhile, Matt Kuchar makes the perfect start with a birdie at the first to go four under while Jason Dufner reaches the same mark after holing his approach at the second for eagle. The crowd are much more excited than the man himself.

6.15pm: A birdie putt, from just a few feet, slips by for Mcilroy at the ninth but it's a 71 and a level-par total at halfway. Scott's birdie effort at eight never threatens the hole but he taps in for par to stay seven under. His playing partner Rose rolls one in for birdie to sit two behind and Robert Garrigus with a birdie-birdie start, is also two back.

Smile, you're one off the lead: Justin Rose fired a superb 66 to sit just off the pace set by Adam Scott

6.10pm: Westwood's been speaking, through gritted teeth, after signing for his 73. He told Sky Sports: 'I played pretty well but the course didn't give me a lot. I got a kick where it hurts in the last two holes. I'm in red figures going into the weekend so I've still got a chance.'

5.55pm: It's a 64 for Simpson - the best of the tournament. He's on four under, three behind Scott once more after the Aussie drops a shot at the seventh. But a brilliant second from the trees right of eight sets up another birdie chance. he's not doing too much wrong.

Digging deep: Phil Mickelson finds the rough stuff during his second round at Oak Hill

5.45pm: Scott finds another birdie - at the sixth - to regain his three-shot lead and Westwood limps over the line, closing with a bogey after missing a tiddler. It looked like we could be in for a ding-dong battle between the two just a few hours ago but a 73 leaves the Englishman seven shots off the pace. His poorest round at The Open came on the Sunday. He'll be hoping this is as bad as it gets here.

5.41pm: A birdie at seven boosts McIlroy's chances of playing over the weekend. He's one over, three better than Luke Donald who appears to be heading home. The former world No 1 has three holes left.

5.36pm: Westwood backers look away now. It's a double-bogey six at the eighth and he falls from joint third to a tie for 11th. He's five shots behind Scott. Rose is now the highest-placed Englishman on the leaderboard as he takes Westwood's place on four under.

5.28pm: Stop the drum roll. Simpson's fluffed his lines with a bogey at the seventh. You never know though. Birdie-birdie finish and it's a 62.

5.18pm: Darren Clarke has finished his second round. It's a 73 for the Northern Irishman and he's just inside the cut mark on two over par.

This from the PGA Tour: Simpson's lowest round in a major is 66 (2011 US Open, 2011 Open Championship). Three pars would be 63.

Cheers for that, PGA Tour people. It should be added that no player has shot better than 63 in a major. Drum roll.......

It never rains but it pours: Luke Donald was heading for another missed cut in a major

5.11pm: Someone's looking down on Simpson. That's another birdie, at the 175-yard sixth hole, and he's within two of Scott's lead. Coral were offering 80-1 on last year's US Open winner. That's now 14s.

5.05pm: Hello Justin! Quiet man Rose has just sneaked right up on us. Three birds on the spin, from the first, and the US Open champ is three under. The weather warning signs have been taken down. Again. But don't get too excited. You know what happened last time.

Watch the puddles: Webb Simpson was staying out of trouble for most of his second round at Oak Hill

5pm: Three holes left for Westwood to find a birdie. Simpson could give him one of the six he's plundered. His latest, at the fifth, takes the American to four under. He's now three behind Scott as the Aussie bogeys the third to cancel out his birdie at the previous hole.

4.51pm: It's a three-shot cushion again for Scott after a birdie at the second, after a putt way longer than that club of his finds the mark, and he's four ahead of Westwood who is still level par for his round.

4.45pm: More on Austin's blunder. The rule is, the player is penalised two shots for each hole where the rule breach occurred. As Austin declared at the third, his four at the first became a six and his bogey-five at the second became a seven. Ouch!

Birdie machine: Webb Simpson was ripping it up during round two of the US PGA Championship

Meanwhile, Manassero is flying up the leaderboard as a birdie at the par-three 15th - his third in five holes - takes him to two under par.

4.35pm: From Webb Simpson to Homer Simpson. Well, Woody Austin, but the 49-year-old has just had a moment our favourite yellow cartoon character would've been proud of. We're hearing Austin had 15 clubs in his bag and has been hit with a four-shot penalty. As I said. He's 49. Old enough to know better.

Hammering down: The rain lashes off the water next to the 15th as Oak Hill becomes Soak Hill during round two

4.25pm: Just watch Simpson go! He's four behind Scott in a tie for sixth after a second straight birdie at the third takes him to five under for his round. McIlroy birdies the same hole but, on three over, he'll need a few more. Poulter is on the same mark after a double-bogey six at the 18th.

4.18pm: Scott fires one into seven feet to set up another birdie chance at 18 but the putt stays above ground and he turns in 33 with a two-shot lead. What about his playing partners? Mickelson is level and Rose one under. Room for improvement from Scott's fellow major men.

4.10pm: Simpson is making steady progress after walking off the second with his fourth birdie of the day and no dropped shots. He's just outside the top 10 on two under and a young Italian has also hit a bit of form. Matteo Manassero is three under for his round - with five holes left - and one under for the championship.

4pm: Kiss of death a few posts ago as far as the weather is concerned. Derek says: 'Oh well. No sooner do the weather warning signs come down than it starts raining harder than ever. Talk about a Michael Fish moment. Soak Hill now saturated, with water on some fairways. How much longer can this go on?'

Gone for good: Rory McIlroy threw his ball into the water after a bogey at the 15th

3.53pm: First bogey of the day for our leader and Scott's advantage is back to two after he misses from five feet and takes five at the tricky, par-four 17th. But Westwood is three behind after dropping a shot at the second. You wait all day for a bogey then.....

3.48pm: Derek's best snippet yet. The one we've been waiting for: 'Weather warnings that were posted all over Soak Hill about 90 minutes ago have been taken down. The rain has all but stopped. Looking at the forecast, it looks like the bullet has been dodged.' Good news for the fans in our picture below.

Cheers: Adam Scott celebrates his birdie on the 13th green in front of a gallery full of umbrellas

3.40pm: More from Derek Lawrenson at Oak Hill: 'Some players must be looking at Scott’s score and wonder if he’s playing the same course. Eight under at this stage is crazy-good. Westwood is playing out of his skin and still finds himself three behind, although Scott has still to play the difficult 17th and 18th. What price these two separating themselves from the pack this weekend and having a little Ashes duel all their own?'

By the way, if you're interested, England are 155-4 at tea in Durham.

3.35pm: Great Scott, Scotty is beamed up, take your pick, they all work. The Aussie, who started at the 10th today, is three clear of Westwood and Furyk after a third birdie in his first seven holes.

3.30pm: Two closing bogeys took the gloss of Martin Kaymer's round yesterday but the 2010 champion, who holed out for a spectacular eagle at the 13th in round one, has just birdied 15 and 16 to reach two under for the day and four under overall.

Straight as you like: Lee Westwood fires his second into the 18th during round two at Oak Hill

3.24pm: Rose gets one back at the 14th and he's back in the red while Ian Poulter has parred four in a row after dropping a shot at the 10th. He's one over and a shot better off than McIlroy, who followed a birdie at 14 with a double-bogey at 15 and a bogey at 17.

3.17pm: Mark Brown is putting together the worst score of the day. Two double-bogeys and three bogeys leave the New Zealander on 14 over.

3.10pm: It had to come at some point and it's taken 27 holes but Westwood has posted a bogey. It's at the 17th and he's two behind Scott.

Don't try this at home kids: German Martin Kaymer leaves just one hand on the club at the 14th

3.03pm: Mickelson has a black glove on each hand to try and fight the wet conditions but we might be about to see those magic paws because, wait for it.... the rain is easing off. The weather warning signs are still up but we'll take all the good news we can get.

2.56pm: Webb Simpson has taken to the wet conditions like a duck to...

That was poor. Apologies. Maybe he's got webbed feet. Anyway, he's three under for his round (after seven holes) and one under overall. Dutchman Joost Luiten is on the same mark after three birdies and a bogey in his first eight holes.

2.50pm: The bookies certainly fancy Scott. Available at 18-1 on Thursday morning, he's no better than 100-30 now. Westwood was as high as 35s but he's 11-2.

2.45pm: Mickelson matches Scott at the 13th to pick up his first shot of the day after three pars. Big Phil is level par.

2.43pm: Are we going to have a curly haired winner of the US PGA Championship for the second year running? Scott is certainly doing his best to make it happen. He's out in front on his own again after a birdie at the par-five 13th.

Doom and gloom: Dark skies, black umbrellas and the weather warning sign at the US PGA Championship

Hand it to him: Phil Mickelson doubles up on the gloves to try and combat the wet conditions

2.37pm: A couple of problems with our leaderboard - I'm blaming the rain - but don't worry, someone is sitting in a dark room pushing button after button to make everything good again. You won't miss a thing.

2.24pm: Justin Rose isn't liking this rain. A bogey-bogey start from the 10th and the US Open champion is back to level par. Francesco Molinari's picked up a shot in his first four holes and he's one over alongside Nicolas Colsaerts. The big-hitting Belgian has parred four in a row after a birdie-bogey start.

Spot the golfer: Jason Day takes shelter under his big brolly as the rain hammers down at Oak Hill

2.15pm: Westwood is refusing to let Scott out of his sight. Another birdie, this time at the 14th, and the Englishman joins the Masters champion on six under. The rain delay halted Westwood's momentum yesterday and I reckon he'll be keen to keep going.

2pm: Tim Clark knows his way round Oak Hill. The little South African was third behind Chad Campbell and winner Shaun Micheel 10 years ago. Clark is two under after breaking a run of three straight pars with a birdie at the 13th.

Still no hooter. Keep those fingers crossed. Do whatever the opposite of a rain dance is.

1.51pm: Scott does get the start he wants though as he moves one clear of the pack with a birdie at the 10th.

And now the bad news. This from our man Derek Lawrenson: 'Hate to be the harbinger of doom, but a real threat there will be a suspension shortly. The rain’s coming down quite hard now. Westwood’s manager Chubby Chandler came out with no rain gear and looked thoroughly soaked and miserable after four holes. At least his man was doing his best to cheer him up with that curling 25-footer for birdie at the 12th. Wouldn’t it be typical of Westy’s luck if, having made a good start, the siren to suspend play blows?

Raining champion: It was wet and miserable when last year's US PGA winner Rory McIlroy teed off on Friday

1.44pm: Jimenez doesn't flirt with the leaders for too long. He hits reverse with a five at the par-three 11th but his numbers, like the wine he loves so much, are still red.Unlike Mr McIlroy's. Rory doesn't get the start he wanted as a bogey on 10 takes him back to level.

1.41pm: Right, here we go. Just like that there's five guys in a tie for the lead and one of them is Westwood. He birdies the 12th - his third - to hit five under and Piercy is on the same mark after erasing memories of his opening bogey with a run of three straight birdies from the fourth.

1.32pm: And the pics are coming in. You'll see just how grey it looks in upstate New York. Scroll down.

It's getting heavy: After a fortnight of sun in Scotland, Phil Mickelson is back in the USA - where it's pouring

1.30pm: Day joins his fellow Aussie Scott and Furyk at the top after his second birdie in three holes. He might take for ever but he gets the job done. It's a par-par start for Westwood and Clarke is up to two under after a birdie at the fourth.

1.25pm: Miguel Angel Jimenez is off to a flyer. The veteran Spaniard, who led The Open at the halfway stage before fading, is two off the lead after a birdie at the 10th. Can he keep it going this time? I'd love it if the answer was 'yes' but... we'll see.

Out in front: Adam Scott and caddie Steve Williams keep dry as they plan their attack on Friday morning

1.15pm: As promised, a much better pic of the pin positions. But the pink one can stay to add a splash of colour until we start getting the good shots through of Oak Hill in all its glory. Scroll down.

It's a steady start for Westwood, a par at the 10th and he's on his way. Rory McIlroy has just teed off at the same hole. The defending champion shot a 69 yesterday with five birdies and four bogeys. What an event this would be for the young Northern Irishman to bounce back from his recent loss of form.

Up and under: You can see the umbrellas in the background as Lee Westwood tees off at the 10th

1.05pm: Day, with two top-three finishes in majors this year, moves to within a shot of the lead with a birdie at the 10th.

1pm: The pin positions are in and the picture will be just below in a matter of moments. But I'll warn you, it's a funny-looking pink colour. I'll try and post a better version as soon as I get one.

Shake on it: Lee Westwood (left) and playing partner Bubba Watson on the tee ahead of their second round

Old head: Miguel Angel Jimenez was out early on Friday looking to make a move on the leaders

12.55pm: So much for the whole 'it won't rain' thing. This from our man Derek Lawrenson: 'Soft summer rain greeted all the early starters here at Rochester, with the forecast predicting it will last for much of the morning. There is a ‘slight chance of a thunderstorm’ but hopefully we will not get unlucky. With the rough wet and lush, keeping it on the fairway is imperative. I’m off to watch Westy to see if he can repeat the wonderful ball striking he showed on day one. Fingers crossed he has the ball on a string once more.'

US PGA Championship: Pin Positions for round two at Oak Hill

12.45pm: Welshman Jamie Donaldson has withdrawn before the start of his second round. Donaldson shot 80 yesterday and has cited a back injury as the reason for his early exit. He joins Bo Van Pelt who conceded defeat in his fight with a hip problem.

12.40pm: Four posts in before Tiger Woods gets a mention - that must be a record. Woods is six shots behind but the gap could be a lot wider by the time he tees off at 6.45pm. Scott goes at 2.35pm, Westwood is on his way to the tee and Jason day, on three under, has just teed off.

Meanwhile, young Japanese star Ryo Ishikawa - he's only 21 but he's been around for ages - has plummeted down the rankings but he's heading in the right direction today as a birdie on 11 takes him to two under.

Round two: Pin positions for Friday at Oak Hill

12.30pm: The opening group make hard work of the first with Brown's double bogey taking him to nine over (Mark's definitely heading for a free weekend) while Piercy and Koepka drop a shot each.

12.15pm: I'll hopefully have the pin positions for you just shortly but first, the weather forecast. Yesterday's 70-minute rain delay was annoying. Don't get me wrong, we're not talking annoyance levels like say, Justin Bieber's face or Dale Winton's voice, but nobody likes the sound of a hooter. Cloudy without rain seems to be the early call but I'll keep you posted.

12pm: Good afternoon and welcome back to MailOnline Sport's coverage of the 95th US PGA Championship. We've got 10 minutes before the first group - Mark Brown, Scott Piercy and Brooks Koepka - tee off and another five before the guys starting on the back nine get going.

American Piercy is the best of the early birds, three under and just two off joint leaders Jim Furyk and Adam Scott.

Daren Clarke, Paul McGinley and Tom Watson make up the second group starting at the 10th with the 2011 Open champion just four off the pace.

Lee Westwood fans don't have long to wait as he's off at 12.55pm and Clarke said last night that the Englishman deserves a major. Having backed Lee at 33s, I couldn't agree more Darren.
